NTE7101
Integrated Circuit
AF Power Amplifier, 7W
Description:
The NTE7101 is an audio power amplifier in an 8−Lead SIP type package designed for use in car radio
and car stereo applications. This device features a low thermal resistance providing easy design for
2Ω load circuits and 4Ω load BTL circuits.
